Can't play youtube videos all of a sudden

I just got that problem aswell.
I know this wont help you, but it might help me.
My ipod touch has not gotten the recent update, do you think that could be the reason?

I've been having the same problem and I do have the latest update. It either says the video won't play, or it only partially loads, plays for 2 seconds and then stops. I've added quite a few more apps since youtube was working when I first purchased the ipod, however. So is there not enough room on my ipod anymore for the videos to finish loading? There is at least 1GB free space yet.

I have a 2nd gen iPod touch running 2.2 and i also have this problem. i noticed it around 5am UK time.

i can, however, confirm that this is not a problem that is just isolated to the iPhone / iPod touch. I have an G1 phone running Android, and this is unable to view any YouTube videos.

since this is a problem that transcends platforms, it would appear that there is a problem at YouTube/Google's end, and as such i implore you all to forward your problems with YouTube over to their discussion forums and make them aware of the problem

I have an iPhone and an iPod Touch, both just a month old. They have both been playing youtube content without a glitch over the same wireless network. The iPod still does, but the iPhone gave in, from one minute to the next, early this morning (CET). All youtube content refuse to play back with the message "This movie could not be played", but, strangely, ONLY on the iPhone. Just tested it again now. iPod fine, iPhone fails. Mail and Safari and everything else is equally fine on both units. Restoring 2.2.1 on the iPhone had no effect... is this a Youtube issue?!?

I have a 2g touch, and it has the same problem. It nust be yutube having problems.

Confirmed the same problem, iPod Touch 2nd Gen, Manhattan Beach, CA. The ISP is Verizon DSL. Same WiFi connection works just fine with my iPhone 3G, but the iPod Touch gets "This movie could not be played" for all YouTube videos.

Short of sniffing the network connection, I'm not sure how to find out what is down.

I could play the you tube videos last night on my itouch 2nd generation but today I get the "video cannot be played" message.

I have an itouch with the same problem of SOME youtube videos getting a "this movie could not be played" message while accessing youtube from Safari.

However, if I access youtube from the icon instead (not going through Safari) the same video can now be watched.

So I would have to say this narrows it down to a Safari (which works fine in all other respects) or a youtube issue.

I can play the youtube videos through safari but if I try to use the youtube icon I cannot/wont let me play them.

problem seems a bit inconsistent then... me too can now only play movies via Safari and NOT directly from the YouTube app. (although when I first encountered the problem this morning it was when I clicked on a YT link in Safari...)

I have now come across a few random movies that will load and play directly in YouTube app. although the loading seems slower than yesterday.

The most puzzling to me is that my iPod Touch, sitting in the same room on the same wi-fi has had no such problems whatsoever...

Just thought I would add I am having the same problem here. Quick solve is to go onto www.youtube.com on Safari, seems a lot better as you can view and post comments on videos and access your favourites. Sweet.

This is weird. I can watch youtube through the icon but NOT Safari but some of you guys can watch through Safari and NOT the icon.

This is starting to seem more and more like an apple problem rather than a youtube problem.

Also, resetting (holding the power and round button till the apple logo comes on) did not resolve the issue.

RESOLVED. I went ahead and did the apple reset AGAIN and viola youtube once again works with Safari.

Yeah, same for me. I just go on youtube in the home screen and it says that phrase.
